AUTOMATIC WRAPPER SEAL AND LOCK SPECIFICATION forming part of LettersPatent No. 784,770, dated March 14, 1905.

Application led March 15, 1904. Serial No. 198,322.

To all whomJ it 'may 0072/067171,.-

Be it known that I, EDMUND FRANKLYN lYEBBER, acitizen of the UnitedStates, anda resident of New York, in the county of New York and Stateof New York, have invented certain new and useful Improvements inAutomatic XV rapper Seals and Locks, of which the following' is'aspeciiication.

My invention relates to improvements in that class of wrapper sealingand locking devices commonly known as seals employed in securing thecontents of envelops or wrappers of parcels, packages, Sac.

lt has for its special object to provide suitable means of substantialprotection by devices adapted for locking and sealing without the aidof'a sealing-press, and l therefore call it an automatic seal.

In the accompanying drawings, Figure 1 represents a top plan view of theouter or exposed seal-plate, which is in this example embossed in ringsand other characters mainly for the purpose of stitfening the thin sheetmetal of which it is made. Fig. 2 is a transverse section of said plateon line 2 2 of Fig. 1, also a section of part of a wrapper to be sealedand a side elevation of an outside staple employed in the sealing. Fig.3 is a top 'plan view of an inside seal-plate. Fig. 4 is atransversesection of said inside seal-plate and a part ofthe wrapper to be sealedand a side view of another staple for application inside to clench withthe outside staple. Fig. 5 is a transverse section of both seal-platesand parts of the wrapper and side views of both the staples inserted,but not clenched. Fig. 6 is a section same as Fig. 5, but with both thestaples clenched. Figs. 7 and 8 are side views of the outside staplerepresented in Fig. 2, one of said views showing a slight modificationof construction. Fig. 9 represents an elevation of the inside staple asseen lookingI in a direction at right angles to the view of said stapleshown in Figs. L and 5. Fig. 10 is a detail in section, on a largerscale, of the two seal-plates and parts of the envelop, showing amodification of the inner seal-plate. Fig. 11 is another detail insection, also on a larger' scale, of the two-seal-plates and part of theenvelop and elevations of parts of the staples illustrating more clearlythe locking features of thc staples.

A represents the outside seal-plate. It is preferably a disk of thinsheet metal and has outer and inner embossed rings a and andintermediate embossed characters c and Z for stiii'ening purposes.Writhin the inner ring?) are two slots c, placed oppositely to eachotherdiametrically of the plate and in parallel relation to each other, andtwo other slots f, similarly placed in a line at right angles to theline of slots e.

B 'represents the inner seal-plate of like disk forni and having slots1,/ and f', corresponding with slots @and ,7" of plate A. This disk ispreferably plain', but it may have its margin turned downwardly, as atg, Figs. 4, 5, 6, and l1, or it may be upturned, as at h, Fig. l0.

In Fig. 9 l represent a fastening-staple, preferably of sheet metal,with prongs /L t0 be inserted from the inside of the wrapper iirstthrough the slots f of plate B, then through the laps /f and 7' of thewrapper, and then through the slots j' of plate A. 'lhis staple haswing-likeextensions of the head t, bent into the hook shape shown inFigs. 4, 5, and 9, so as to occupy the positions shown in said iigu res.ln Figs. 7 and 8 l represent another staple of like material. whoseprongs m are to be inserted iirst through slots e of sealplate A, thenthrough the laps of the wrapper, and then through the slots e' oftheinner seal-plate B, so that the points n extend into the hooksbetween their shanks and points, as best seeninFig. 5. The hooks fandprongs fm of the respective staples are then pressed down bythe iingersof the operator and clenched, as shown in Figs. 6 and 11, and the prongs/t of the inside staple arc clenched down over the head o of the outsidestaple, thus completing the closure of the seal in such condition thatopening and reclosing cannot be effected without clearly showingdistortions manifestly indicating the fact.

The prongs m of the outside seal may be nicked, as shown at o and y), soas to cause further distortion when the closure is effected and toprovide points for more elfectually engaging the ragged edges of thepunctured said prongs and hooks adapted to he clenched on the insideseal-plate by hand-pressure and the prongs of the inside staple adaptedto be I5 similarly clenched on the head of the outside staple and on theoutside seal-plate.
